Build Server

I am currently hosting a build server, and I want to know what people look for in build servers. I want this build server to be one of the best so im going to you guys to ask what you look for when you join a build server. I also want to know strategies of minges. I want to be able to find them fast and stop them. Recently I have been studying minges, looking for their flaws. I want to make sure they do not ruin my server. I am really hoping that I can make a great server for everyone!

Suggestion: Don’t ask that here, but instead do it on your server.

Well right now its fairly dead, and I just want to know what the gmod community as a whole likes to see on build servers.
